compliance with these safety instructions will also lead to forfeiture of any and all rights to claims for damages.
In particular, non-compliance can, for example, result in:
- failure of important machine / plant functions
- failure of prescribed maintenance and servicing practices
- hazard to persons by electrical, mechanical and chemical effects
- hazard to the environment due to leakage of hazardous substances.
Ex symbol relates to additional requirements which must be adhered to when the pump is operated in hazardous
areas.

2.5 Safety instructions for the operator / user
- Any hot or cold components that could pose a hazard must be equipped with a guard by the operator.
- Guards which are fitted to prevent accidental contact with moving parts (e.g. coupling) must not be removed whilst the
machine is operating.
- Leakage (e.g. at the shaft seal) of hazardous media handled (e.g. explosive, toxic, hot) must be contained so as to avoid
any danger to persons and the environment. Pertinent legal provisions must be adhered to.
- Electrical hazards must be eliminated. (In this respect refer to the relevant safety regulations applicable to different countries
and/or the local energy supply companies.)
- Any components in contact with the pumped product, especially in the case of abrasive products, shall be inspected for wear
at regular intervals and replaced by original spare parts (see section 2.7) in due time.
